Flask配置

网络配置

flask网络配置其实主要就是监听网卡这块，是指上就两种方法
1、当本地的网卡只有本机可以访问
2、监听整块网卡，所有机器都可以访问
这也是127.0.0.1和0.0.0.0的区别

from flask import Flask
app = Flask(__name__)
@app.route('/')
def hello():
    return "hello flask,Let's study"

if __name__ == '__main__':
    app.run( host = "0.0.0.0" , debug = True )

如果配置host为0.0.0.0，则监听整块网卡，所有机器都可以访问
不填写只监听本地网卡，只有本机可以访问

Flask配置加载方式

变量配置

from flask import Flask
app = Flask(__name__)
app.config['DEBUG'] = True###############通过这种方式配置
#app.config.update(DEBUG = True,SECRET_KEY = '...')###############还可以更新
@app.route('/')
def hello():
    return "hello flask,Let's study"

if __name__ == '__main__':
    app.run( host = "0.0.0.0" , debug = True )

模块配置

from flask import Flask
app = Flask(__name__)
app.config.from_object('config.base_setting')#通过加载模块的方式进行配置
@app.route('/')
def hello():
    return "hello flask,Let's study"

if __name__ == '__main__':
    app.run( host = "0.0.0.0" , debug = True )

环境变量配置

from flask import Flask
app = Flask(__name__)
app.config.from_envvar('ops_config')#通过加载环境变量的方式进行配置
@app.route('/')
def hello():
    return "hello flask,Let's study"

if __name__ == '__main__':
    app.run( host = "0.0.0.0" , debug = True )

设置环境变量方法
linux主机：export ops_config = local
windows主机：set ops_config = local

文件配置

from flask import Flask
app = Flask(__name__)
app.config.from_pyfile('config/base_setting.py')#通过加载文件的方式进行配置
@app.route('/')
def hello():
    return "hello flask,Let's study"

if __name__ == '__main__':
    app.run( host = "0.0.0.0" , debug = True )
